JONAS NORBERG, OF LATOUCHE, TERRITORY OF ALASKA.

CONCENTRATE-DRIER.

Application filed April 4,

To all whom z'zmag/ concern.' Y Be it known that I, JONAS Nonnne, a citizen of the United States, residing at Latouche, Territory of Alaska, have invented certain new and useful Improvements in Concentrate-Driers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe artto which it appertains to make and use the same.

This. invention relates to a drie-r for drying ore concentrate after the same leaves the filter, sufficiently to permit shipping thereof to advantage.

More specifically, the object of this invention is to provide an ore concentrate drier which includes a pan structure positioned on 4an incline and having rolle-rs carried by its lower end which ride over a track and its upper receiving end connected to a crank shaft which reciprocates, for jogging the pan or carrier structure to cause theore concentrate to travel thereover.

Vith the foregoing and other objects .in view this invention consists in Such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described illustrated in the accompanying drawings and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views and in Vwhich:v Y

Figure 1 is a side elevation of the improved drier having parts thereof broken away j Fig. 2 is a top plan of the drier having parts broken away Fig. 3 is an end view of the drier looking at the receiving end thereof Fig. 4 is an end view of the drier looking toward the delivery end of the drier Fig. 5 is a section of the line 5-5 of Fig. 1

Fig. 6 is a section of the line 7 7 of j rig. 2.

Referring more particularly to the drawi ings, 1 designates the supporting structure of the drier which has a crank shaft 2 rotatably supported by suitable bearings 3 which are carried by the supportingstructurel 1. The crank shaft 2has a gear 4 mounted thereon which meshes with a pinion 5 carried by a shaft 6. The shaft 6 is rotatably supported by Suitable bearings 7 Specification of Letters Patent.

and it has a power pulley 8 mounted thereon through the medium of which power may be transmitted ,to the shaft 6 and to the shaft 2 through the medium of the gears 4 and 5. l

The drier Structure or pan has bearings 11 attached to the under surface of the supporting beams 12 thereof which bearings are mounted upon the wrist of the crank shaft V2, as clearly shown in Figs. 1 and 3 of the drawings.

A plurality of electric plates or heating elements 15 of the usual construction are mounted upon the upper surfaces of the I beams 12 and they have a sheet 16 of metal mounted upon their upper surfaces over which the ore concentrate travels.

As stated, the heating elements 15 are of usual and well known construction and are adapted to be connected to a suitable source of electricity through the medium of the usual binding post and suitable mains and means connected thereto, the mains being connected to the source of electricity by a suitable cord to permit reciprocation of the drier structure, as indicated in the drawings.

Angle strips 17 are attached to the elec tric plates 15 and their horizontal portions rest upon the upper surfaces of the sheet metal plate 16, asclearly shown in the drawings, while their vertical portions provide sides for the pan structure to prevent the ore concentrate from falling off the sides of the pan or drier structure.

The delivery end of the pan or drier structure is positioned, normally, lower than the receiving end and it has bearings 19 attached to the under surfaces of the I beams 12, which bearings support an axle 20. Suitable flanged supporting wheels 21 are mounted upon the axle 2O and ride upon T-rails 22 which are supported by a supporting structure 1.

Rotation is transmitted to the crank shaft 2 from any suitable prime mover, through the shaft 6 which rotation imparts a jogging movement to the drier pan of the concentrate drier and this jogging movement keeps the ore concentrate traveling downwardly over the upper surface of the sheet metal plate 16. The electric plates 15 heat the plates 16, which causes the evaporation of the greater portion of the moisture of the ore concentrate, delivering the concentrate from the lower delivery end of the drier pan in condition convenient for shipment.

Having thus fully described theY invenv tion what is Claimed is:V l

l. An ore concentrate' drier comprising a supporting structure, an inclinedidrier pan above said supporting strueture,'means beneath one end of said drier pan to permit of the saine longitudinally of Said support-` ing structure, an operating crank shaft mounted beneath the remaining end of said drier pan to cause a Ystarting,- movement thereof, means 'for' operating said Crank shaft, and a heater element mounted beneath and adapted for movement vwith said drier pan. Y v

2. An ore concentrate drier comprising a supporting structure havingv rails, an inclined drier pan positioned above said supporting structure and inoludingal bottom plate, an electric heater secured to the under face oi said bottom plate toy supply heat thereto, a transverseshaft; mounted beneath the lower end of Said drier pan, and heater,
